Deck the halls with sugar, butter and chocolate as competitors from past seasons of "The Great British Baking Show" prepare sweet Yuletide treats for the show's judges.
The ghosts of bakers past - Rosie, Jamie, James, and Ruby - whip up miniature panettones, Christmas puddings and delightfully deceptive illusion cakes.
Old acquaintances are not forgotten as faves Henry, Nancy, Rahul, and Helena make fruit crumbles, bao buns, and cakes representing their 21st birthdays.
